(no subject)

I just had a look at the Transformers wiki and couldn't find the information I was hoping for there. Does anybody know off the top of their heads if there's a canonical age or timeframe given for any of the Bayverse characters? I'll pull their ages and related numbers out of the air if I have to, but if there's an established age reference for that particular universe I'd like to at least know what it is before accidentally dismissing it out of hand.
